Saudi Arabia's Interior Ministry offered Wednesday a $1.3 million reward for information leading to the arrest of sixteen suspects allegedly involved in the bombing of a Shia mosque last week, Reuters reports.
On May 29 a car laden with explosives killed at least four people when it detonated outside Dammam’s al-Anoud mosque during Friday prayers.
Daesh later claimed responsibility for the attack via Twitter.
One week earlier, a suicide bomber killed 21 worshipers at a Shia Mosque during Friday prayer in the Saudi province of Qatif.
Daesh later released a statement also claiming responsibility for the attack and identified the bomber as Saudi national Abu Amer al-Najdi.
The statement said “soldiers of the caliphate” were responsible for the attack, in which a suicide bomber “detonated an explosives belt” in the Imam Ali mosque during Friday prayers in the Shia-majority city of Qatif.
